The Waterfall chart is a good visualization to show you changes on value over a sequence, The sequence can be time, or date or workflow steps, etc. However, the chart shows you information more than that. Since one of the common business requests is to perform different comparisons between various time periods, I would say that Power BI has a lot to offer in this regard. @joshcorti11there is no concept of almost perfectly, it is working or not, you have to use calculation group, maybe with 4 calculation items: The top 3 are self-explanatory, and in the 4th one, use the range from date slicer and then do the comparison for the same period as you are doing now. to follow Vizartpandeyon Instagram! The light blue line is showing the current period and the dark blue line is showing the previous period in the visuals.

STR( MIN(if DATETRUNC(day, [Order Date])>= [Start Date] THEN [Order Date] END)) + +STR(MAX(IF DATETRUNC(day, [Order Date])<=([End Date]) THEN [Order Date] END )), STR( MIN(if DATETRUNC(day, [Order Date])>=DATEADD(day,-[Days Inbetween SD and ED],[Start Date]-1) THEN [Order Date] END)) + + STR( MAX(IF DATETRUNC(day, [Order Date])<=([Start Date]-1) THEN [Order Date] END)). This article introduces the syntax and the basic functionalities of these new features. Reza.

Knowing the current month of a cell in the visualization, the previous month is the maximum month number available in the filter context provided by ALLSELECTED excluding the current and following months. If you are using Excel 2010/2013 or Analysis Services Tabular 2012/2014, you have to write the PY Last Day Selection without the variables. DateAdd used in a example below to return the period for a month ago. This is an example of using ParallelPeriod: For every month, the ParallelPeriod expression will return a month before that, because in the parameters, we mentioned the month before: ParallelPeriod can be used to fetch the Sales of last month like this: As you can see in the above screenshot; ParallelPeriod will return sales of the entire last month, even if you are looking at the day level.

One of the challenges that new users have when using Power BI is to decide if they should use Power Pivot (DAX modelling) or Power Query (PQL shaping) to solve each problem . 40213 Dsseldorf Next easy step is understanding number of days between start and end of period, which is simply by using DateDiff() DAX function as below; I add them all in the report as Card Visuals (one for each measure), and here is the result so far; After finding number of days in this period, start, and end of current period, it is a simple calculation to find the previous period. You can see we are comparing each day's current year and previous year, for example, on February 1st, there was an amount of 160 this year and 150 last year: For the given date of 14th of December 2005, the QTD gives you the sum of sales from 1st of October to 14th of December 2005. and the previous QTD gives you exactly the same period in the previous quarter (from 1st of July to 14th of September 2005).

[DaysInterv] = DATEDIFF( MIN ( Calendrier[Date] ) ; MAX( Calendrier[Date] ) ;DAY ), [Previous Period Sales] = CALCULATE( [Total Sales] ; DATESINPERIOD(Calendrier[Date];MIN(Calendrier[Date])-1;- [DaysInterv]- 1;DAY) ), Hi Tristan, When the durations of both time periods are different, we should adjust the values to make a fair comparison. To understand the current period, an easy way can be calculating start, end of period and number of days between these two. As an example; if user selected a date range from 1st of May 2008 to 25th of November 2008, the previous period should be calculated based on number of days between these two dates which is 208 days, and based on that previous period will be from 5th of October 2007 to 30th of April 2008. Now add a slicer for FullDateAlternateKey in the page. SamePeriodLastYear returns the equivalent period to the filter context from last year. such advanced charts.
